The elements 15, 16 are freelyfopenH at their outer edges and the upper Walls of the yunits merge into thegside sheets `of the water legs VWhile the flower Walls arevturned downwardly and as shownare secured to the mud ring. f f

In the form shown in iny patentreferred to y the Water bottom structure is supported by slings passing beneath the same` which may v be secured to the mud ring frameof the boiler. According to the presentl invention a structure is provided Which will be self-'supporting andin which the slings or the supporti-ng l vreferredto will be unnecessary.` To this end .Y and'to holdltheloiver edges of the unitsl properly spaeech'members"'l9,`20 are provided' one of which is shown in perspective inFig.

Y 4.1] Asthere shown the members presentan angular conformation having vertical web 21 andafhorizontal web 22; f

The ends` of members 19', 20 are icutaway. i

to provide arcuate recesses'ZS7 Qdiand the portions 2'5, 26 atthe upper Vside of the recesses 1 arebevele'd tojseat againsttlie rounded end Walls of the units inthe manner illustrated in Fig. 3. `Also the endsQ-QS ofwveb 2Q are shown yas beveledto seatI against the roundedl surface ofthe 'tubular members 17, 18. i

`A In addition, a lug 29, 30 is provided in the bottom'of'each recess 23, 2a to contactwitlrthe l Atubular member. 17, lirandv to* secure an accurate spacing ofltheselugs during assembly. After. the spacing members are in'gplace and infirm contact With the units'l, 16; the ends 25, 26, 27, 28` thereof are Welded tothe units and thesurfaceof the recesses 23,24 arealso Welded, 'the Welding material `b y 30 so as to ina-kefhe entire jointjair-tight. y

' bottoni plate 3l' is shown tothe' web 2Q y the margins 82` 'of the vplate 3.1` beingy turned tolap upon thecylindrical portions 1?, A18 of imits'I,` 16 as clearly.'illustrated? in Fig. 3," l

plate y31 serves asja connection between the Water bottom units completing 1an inverted seing` used to which :is riveted of the spacing Vmembers 19,220', f

`said margins being'evelded tothennits.4 The y truss therewith, forms an air-tight closure for the space between the unitsfand supports the refractory filling 119.

Transverse plates 83, 34 are shown riveted tothe web21 of spacing members 19, 20,-the 'ends of the plates being secured by angles to lthe inside side sheets-:of the boiler and upon said plates angles 35, 36:are secured to support yhorizontal plates 37, 38v upon which brick ingan opening therein for Va fluidfuelvburner Vlfirejbriek or other form of refractoryn` is work to complete theN enclosure of the fire-y boX is supported. i v
